GANG-PLOW.

To a whom it may concern.-

Be it known that I, GEORGE W. HAMMERS,

acitizen of the United States, residing at La Junta, in'the county of Otero and State of Colorado, have inventeda new and useful Gang-Plow, of which the following is a specification.

This invention relates to gang-plows; and its object is to provide a durable and compact machine of this character having the plow-beams so mounted as to be capable of lndependent vertical movement.

A still further object is to provide lowbeams which are incapable of movin aterally within the frame of the plow an which can be simultaneously adjusted to regulate the incline of the shares and the depth of the cut.

Another object is to provide m'eans-where by the plow beams and shares can be quickly raised and lowered simultaneously by means of motive fluid adapted to be directed from the traction-engine to be used in connection with the plow.

A still further object is to provide simple means for adjusting the frame of the plow toward or'from the ground. a

With the above and other objects in view the invention.,consists of certain novel features of construction and combinations of parts, which will be hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings,' Figure 1 is a side elevation of a gang-plow constructed in accordance with the present invention. Fi 2 is a plan View thereof, a portion of the platform being removed. Fig. 3 a section on line 3 3, Fig. 2, and showing by dotted lines the position of a plow when raised from the ground.

Fig. 4 is a. detail view of a plow-beam and showing by dotted lines a position assumed thereby w lation to the ground. Fig. 5 is a transverse section through two plow-beams and showing the yoke connection therebetween. Fig. 6 is a view, partly in sectionand partly in rear elevation, of the rear guide and lifting device of one of the plow-beams, said beam being shown in section; and Fig. 7 is an elevation of the front guide of one of the beams, saidbeam being shown in section.

Referring to the figures by characters of reference, 1 is'a short side beam, and 2 is a long side beam, both beams being connected Specification of Letters Patent. Application filed October 6,1906. Serial No. 387,606.

' at their front portions by cross-beams 3 and 4, thereby forming a frame carrying a platform 5 of trapezoidal form. A short axle 6 extends from the long side of the frame and is supported by a traction-wheel 7, while an L-sha ed axle 8 is mounted within a sleeve 9, or otherwise secured to the short side of the frame and has its laterally-extending portion arranged within a furrow-wheel 10. The upper portion of the axle 8 is screwthreaded,- as shown at 11, and is engaged by an adjusting-wheel 12, rotatably mounted upon the upper portion of the sleeve 9 and held in place thereon by a ring 13, which is connected to the sleeve by arms 14. By rotating this whee-l 12 the axle 8 can be raised or lowered so as to adjust the wheel 10 to furrows of different depths in order to maintain the machine horizontal.

A beam 15 is arranged diagonally within the side beams 1 and 2 and parallel with the rear edge of the platform 5, and secured to this beam at regular intervals are guides 16, consisting of parallel hangers 17. These hangers 17 have integral heads 18 bolted or otherwise secured to the beam 15 and are provided with an integral base 19, adapted the shaft 22 and through a slot 27 in the plat:

form and constitutes means whereby said shaft can be conveniently rocked manually.

Each fork 25 embracesand is pivotally connected to the front end of a plow-beam 28,

ICO

arranged under the platform 5 and extending through the adjacentv guide 16. Aplowshare 29 is connected to the rear portion of this beam in the usual manner, and as all of the beams 28 areof the same length it will be obvious that the plowshares will be disposed in a line extending parallel with the rear diagonal edge of the platform 5. Each beam 28 has a yoke 30 secured to one side thereof adj acent its rear end, and said yoke is slidably mounted within a strap or eye 31, secured to one face of the adjoining beam 28. A yoke IIO spring is disposed within each loop and bears upon the beam therein, so as, to'eXert a constant downward pressure upon the beam. These loops 34 are disposed at the lower ends of stems 36, which are pivotally connected to arms 37, secured to a shaft 38, which is j ournaled in bearings 39 on the plat form 5 and disposed-parallel with and adjacent to the rear diagonal edge of said platforni. The arms are all disposed in the same plane and are adapted when the shaft is.

partly rotated to simultaneously raise or ower the loops 34 and cause a correspondingmovement ofthe rear ends of the beams 28. A lever 40 is secured to the shaft 38 and carries a spring-pressed dog 41, which normally as the parts have been adjusted in this man-' engages a toothed bar 42, secured to the platform. An operating-cord 43 is connected to the dog and is of sufficient length to permit an operator at some distance from the plow to readily disconnect the dog from the bar 42.

Mounted in suitable supports 44 on the platform 5 is a cylinder 45, having a piston,v

therein, (not shown,) the rod 46 of which is connected to a block 47, mounted in a suitable guide 48, arranged upon ,theplatform This block has upstanding ears 49, which are connected to the lever by a rod 50. Pipes 5.1

open into the cylinder adjacent the ends thereof and are adapted to be connected by flexible hose (not shown) with the boiler of a traction-engine.

may be controlled.

A bracket 53 is secured'to the front end of the frame of the gang-plow, and a chain 54 is adapted to be used for connecting the bracket with the traction-engine. A caster 55 isv connected to the rear end of the beam'2 and is adapted to support the rear portion of the platform.

In use the gang-plow herein described is connected to a traction-engine by means of a short chain 54, and the pipes 51 are coupled to the boiler by means of a suitable flexible hose. When the machine is started forward, fluid 'under pressure is directed into the front end of the c linder 45 so as to drive the piston and the b ock 47 rearwardly and.

cause the lever40 to rock the shaft 38 and swing the arms 37 downward. course necessary for the operator to first disengage the dog 41 from the bar 42. As soon ner the dog is. released and locks theshaft 38 agamst further movementf As will be obvious, the plow-points are simultaneously to the machine.

Each pipe has a'valve 52, whereby the passage of fluid under pressure' pressure upon the dropped as a result of this movement of shaft 38, and the springs 35 will push them into the ground, so that as the machine moves forward a plurality of furrows will be produced. By. permitting each plow tomove vertically and, independently of the others it is possible for the plows to ride over any unyieldingobstructions which may be in the path thereof Without resulting in inj The plows may be ad usted to any desired angle to the round by manipulating the lever 26 and roc 'ng shaft 22. This is clearly illustrated in Fig. 4.

ground simply by releasing the dog 41 and directing fluid under pressurc'into the rear end of the cy inder so as'to swing the arms 37 -All of the plow-points can be raised from the I upward. The wheel 10'i's adapted to ride within one of the furrows previously formed,

and by rotating the wheel 12 the tractionwheel 10 can be'adju'sted so as to hold the frame horizontal. Thezguides' 16 prevent the beams from twisting at the front ends thereof, and, as heretofore stated, the yokes 30 .and 32 constitute effective means for preventing lateral movement of the-rearends of" the beams. Considerable importance, is 'attached'to the fact that all of the beams may be raised or lowered simultaneously by.

means of fluid under pressure, but are at'the same time capable of independent and vertical movement. Importance is 1 also attached to the novel means for simultaneously ad ust1ng all of the beams so-as to bring the points of the plows at different. angles to the ground. By,providing the described mechanisms for producing these results the plow i can be very easily and quickly manipulated.
